Operating ranges define those limits between which the func-  
tionality of the device is guaranteed.  
1. Minimum DC voltage on input or I/O pins –0.5 V. During  
voltage transitions, the input may overshoot V to –2.0 V  
SS  
for periods of up to 20 ns. Maximum DC voltage on input  
and I/O pins is V + 5 V. During voltage transitions, input  
CC  
and I/O pins may overshoot to V + 2.0 V for periods up  
CC  
to 20 ns.  
2. Minimum DC input voltage on A9 is –0.5 V. During voltage  
transitions, A9 and V may overshoot V to –2.0 V for  
PP  
SS  
periods of up to 20 ns. A9 and V must not exceed +13.5  
PP  
V at any time.  
Stresses above those listed under “Absolute Maximum Rat-  
ings” may cause permanent damage to the device. This is a  
stress rating only; functional operation of the device at these  
or any other conditions above those indicated in the opera-  
tional sections of this specification is not implied. Exposure of  
the device to absolute maximum ratings for extended periods  
may affect device reliability.
